The Strength Equipment Every Commercial Gym Needs, From a Strength Coach

Every successful commercial gym I've worked with has the same foundation: power racks with platforms, a full dumbbell range, plate-loaded machines for heavy compound lifts, and selectorized machines for isolation work. The gyms that struggle usually get one of these wrong. They go all-in on one type of machine, skimp on dumbbells, or buy one of everything instead of two of what members actually fight over. If you're opening or expanding a gym, the strength floor is where members decide whether your gym is worth the drive.

My name is James and I've spent 6 years as a strength coach, training swimming, baseball and basketball  athletes and working inside gyms of every size. Now, at Repetition Fitness, I help gym owners design and equip their strength floors. This list comes from what I've seen work on real gym floors, not from a catalog.

What successful gyms have in common

One gym I've worked with is Elite Performance Club in South Gate, California, a private gym that runs strength training, HIIT classes, and personal and small-group training. We did the design, financing, equipment selection and installation. What stands out there, and at every successful gym I've been part of, is that members aren't choosing between plate-loaded and selectorized machines. They use both in the same workout. They'll start on a hack squat, move to a leg extension, and finish with dumbbells. A gym that only offers one style forces members to train around the equipment instead of the other way around.

EPC has also announced a major expansion to a 12,000+ sq ft facility with more than 15 new machines, a turf area, a Pilates and yoga studio, and a sauna. Gyms with a strong equipment reputation are often the ones that end up expanding, because members keep coming.

1. Free-weight foundation

Power racks or half racks with platforms. Squats, bench, presses, and pulls all start here. Plan at least [your recommendation, e.g., one rack per X members] and put platforms under them so members can deadlift without damaging your floor.

Olympic bars and plates. Get more bars and plates than you think you need. Members shouldn't have to strip someone else's bar to start their workout.

A full dumbbell range. This is the most-used equipment in almost every gym I've been in. Go up to at least 100 lb, and for a strength-focused gym, past that. A rack that stops at 50 lb tells serious lifters the gym isn't for them.

Flat and adjustable benches. You can't have too many. Benches get dragged everywhere.

A Smith machine. Useful for beginners, for members training without a spotter, and for exercises like split squats and incline presses.

2. Plate-loaded machines

Plate-loaded machines are what serious lifters look for when they walk into a new gym. They handle heavy loads, follow natural movement paths, and feel closer to free weights. The ones I'd prioritize:

• Leg press. One of the most-used machines in any gym.
• Hack squat or pendulum squat. Lets members train legs hard without the balance and technique demands of a barbell squat.
• Iso-lateral chest press. Independent arms let members train each side and fix imbalances.
• Iso-lateral row or T-bar row. Heavy back work with support for the lower back.
• Hip thrust or glute drive machine. Huge demand right now, and setting up a barbell hip thrust on a bench is awkward and takes up space.
• Belt squat. Loads the legs without loading the spine, which is great for members working around back issues.

3. Selectorized machines

Selectorized, or pin-loaded, machines are how beginners get comfortable in a gym and how experienced lifters finish a workout. Changing the weight takes a second, which makes them ideal for drop sets and supersets. The essentials:

• Leg extension. Every gym needs one, and busy gyms need two.
• Leg curl. Seated or lying, and ideally both.
• Lat pulldown. A staple for back training at every level.
• Seated cable row.
• Pec fly and rear delt combo. Two movements in one footprint.
• Hip abductor and adductor. Consistently busy in almost every gym I've worked in.

4. Cables

A dual adjustable pulley or cable crossover station covers dozens of exercises in one footprint. Successful gyms tend to have more cable stations than you'd expect, because members use them for everything from face pulls to single-arm work.

5. The extras that separate good gyms from great ones

A glute-ham developer or back extension, a dip and pull-up station, a landmine attachment, and a turf strip for sled pushes and carries. None of these is expensive, and members notice when they're missing.

Two of what's popular beats one of everything

The most common mistake I see is buying one of every machine in the catalog. The result is a gym full of equipment nobody waits for and lines at the leg extension and racks. Before you add a new machine, ask whether you need a second of something members already use. If you're expanding, keep, refurbish or replace your current equipment walks through auditing what you have first.

Choosing brands

For plate-loaded equipment, Hammer Strength has the name recognition serious lifters look for. For strength equipment with strong value, we often recommend Skelcore. Technogym's Pure Strength and Selection lines suit premium facilities. Many gyms mix brands, and that's fine as long as the layout works. See our comparison of selectorized vs. plate-loaded machines for more on how they differ.

Layout matters as much as the list

Group equipment by body part so members can move between machines without crossing the gym. Keep racks and platforms away from walkways. Put the most popular machines where people can see them from the entrance, because that's what sells memberships on a tour. We build every strength floor in a 3D layout before anything ships.

Frequently asked questions

Does a commercial gym need both plate-loaded and selectorized machines? In my experience, yes. Every successful gym I've worked with has both. Members use plate-loaded machines for heavy compound work and selectorized machines for isolation, beginners, and quick weight changes.

What's the most important strength equipment for a new or expanding gym? Racks with platforms, a full dumbbell range, a leg press, a leg extension, a leg curl, a lat pulldown, and cable stations. Then add plate-loaded machines based on your members.

How heavy should dumbbells go in a commercial gym? At least 100 lb. Strength-focused gyms should go higher.

How much does a commercial gym strength floor cost? It depends on size and brand. Full equipment packages typically run from $50,000 for a boutique studio to $700,000 or more for a large facility. See our commercial gym equipment guide.
